I have a 2016 520d touring. I use the usb point to charge my iPhone 12. I use Spotify and maps, lately I noticed its doesn't seem to charge my phone, although I very rarely go on long journeys. I took my car to Liverpool a 3.5hr drive, using maps and music, by the time I had arrived, the phone was out of charge. It was plugged in the whole journey. It charged no problem in the hotel. I use an after market cable, someone told me it could be that. When its plugged in, the phone shows it is charging. Can you upgrade the usb point to a usb 2. Thanks
